Videos from the scene showed a large crowd gathered outside the office as the protest intensified.
The Trinamool Congress alleged that BJP workers were behind the demonstration, while the BJP denied the charge.
Mahua Moitra's defiant response
As the unrest continued, Mahua Moitra appeared at a window of her office holding the Trinamool Congress flag in a symbolic show of defiance.
Ignoring the protesters outside, she repeatedly shouted, "Trinamool Congress zindabad," while waving the party flag. Videos of the moment quickly went viral on social media.
The Trinamool Congress also accused police personnel present at the spot of remaining largely passive despite the escalating situation.
Mahua Moitra alleges BJP attack
Sharing videos of the incident on social media, Moitra alleged that "BJP goons" had gathered outside her office for over an hour before pelting eggs and stones.
Hello @DGPWestBengal @WBPolice past 2 hours & your police is watching the fun & not dispersing the mob. They want me to flee & they will pelt eggs /stones while I enter my car. Please do your job. Disperse the mob. Am in NH Dhaba Plassey. pic.twitter.com/PWmjuJEnaH

She claimed the attack was an attempt to intimidate her and asserted that such tactics would not deter her from carrying out her political work.
BJP rejects allegations
The BJP dismissed the Trinamool Congress' allegations, claiming the protest reflected growing public anger against the ruling party in West Bengal.
Party leaders maintained that the demonstration was a spontaneous expression of people's resentment and accused the TMC of trying to portray itself as a victim for political mileage.
“Our party has no agenda to throw eggs on TMC leaders. The TMC faction which remained deprived of the loot is pelting eggs on the other faction which was heavily benefitted from the previous regime. How much police would control them? Where have the top TMC leaders gone?,” West Bengal BJP president and Rajya Sabha MP Samik Bhattacharya said.
Abhishek Banerjee condemns incident
Trinamool Congress national general secretary and MP Abhishek Banerjee strongly condemned the incident, alleging that a "BJP-sponsored mob" had attacked Mahua Moitra's office.
Questioning the role of the police, Banerjee said attempts to intimidate Trinamool leaders through violence and vandalism would not succeed and asserted that the party would continue to resist such actions.
I strongly condemn the attack on MP @MahuaMoitra. The silence of the WB Police, despite the High Court’s recent direction to the DGP to ensure appropriate safeguards, raises serious questions.
